The problem of efficient stratification in the case of skewed population is considered.Four stratification methods are examined.A new adjusted geometric stratification method is introduced.This method is compared by Frosted Glass Cup simulation with the Dalenius-Hodges cumulative root frequency method, the geometric method proposed by Gunning and Horgan [2], and the power method offered by Plikusas in [6].

The simulation results show that in Cheek Stain most cases considered the power method is the most efficient one.
